Airworthiness Directives; Bell Textron 

Canada Limited (Type Certificate 

Previously Held by Bell Helicopter 

Textron Canada Limited) 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Bell Helicopter Textron Canada Limited 

(now Bell Textron Canada Limited) 

Model 206A, 206B, 206L, 206L–1, 

206L–3, and 206L–4 helicopters. This 

AD was prompted by a report that a 

certain tail rotor disc assembly, sold as 

an alternate part, does not conform to 

the approved configuration. This AD 

requires determining if an affected part 

is installed (by doing a maintenance 

records check or inspection), and if an 

affected part is found, replacement with 

a non-affected part. The FAA is issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective August 27, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain documents listed in this AD 

as of August 27, 2021.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a supplemental 

notice of proposed rulemaking (SNPRM) 

to amend 14 CFR part 39 by adding an 

AD that would apply to certain Bell 

Textron Canada Limited Model 206A, 

206B, 206L, 206L–1, 206L–3, and 

206L–4 helicopters. The SNPRM 

published in the Federal Register on 

May 7, 2021 (86 FR 24560). The SNPRM 

proposed to require determining if an 

affected part is installed (by doing a 

maintenance records check or 

inspection), and if an affected part is 

found, replacement with a non-affected 

part. The SNPRM also revised the 

format, rearranged certain paragraphs, 

converted a certain table to paragraph 

format, and removed certain language. 

The SNPRM was prompted by a 

significant amount of time elapsing 

since the notice of proposed rulemaking 

(NPRM) (75 FR 52914, August 30, 2010) 

was issued, requiring the FAA to reopen 

the comment period to allow the public 

a chance to comment on the proposed 

actions. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, issued Canadian AD CF– 

2010–07, dated February 24, 2010 

(Canadian AD CF–2010–07), to correct 

an unsafe condition for certain Bell 

Helicopter Textron Canada Limited 

(now Bell Textron Canada Limited) 

Model 206A, 206B, 206L, 206L–1, 

206L–3, and 206L–4 helicopters. TCCA 

advises that a certain tail rotor disc 

assembly, sold through Bell Helicopter 

Spares beginning March 2009, as an 

alternate, does not conform to the 

approved configuration. TCCA stated 

operating a helicopter with the affected 

tail rotor disc assembly could result in 

loss of control of the helicopter. 

Accordingly, the Canadian AD 

requires determining if an affected part 

is installed, and if an affected part is 

found, replacement with a non-affected 

part. 

Discussion of Final Airworthiness 

Directive Comments 

The FAA received a comment from 

one commenter, Bell Textron Canada 

Limited. The following presents the 

comment received on the SNPRM and 

the FAA’s response to the comment. 

Request To Add a Statement for 

Operators That Already Complied With 

the Actions 

Bell Textron Canada Limited 

requested that the FAA add a statement 

to the effect that if the actions in Bell 

Helicopter Alert Service Bulletin 206– 

09–123, Revision A, dated June 10, 

2009; or Bell Helicopter Alert Service 

Bulletin 206L–09–157, Revision A, 

dated June 10, 2009; have already been 

accomplished then the intent of the AD 

is met and no further action is required. 

The commenter stated that many 

operators will have already complied 

with the intent of the proposed AD 

since the service information was 

released in 2009. 

The FAA acknowledges the 

commenter’s request and agrees to 

clarify. Paragraph (g) of this AD requires 

accomplishing actions using Bell 

Helicopter Alert Service Bulletin 206– 

09–123, Revision A, dated June 10, 

2009; or Bell Helicopter Alert Service 

Bulletin 206L–09–157, Revision A, 

dated June 10, 2009. Paragraph (f) of this 

AD states to accomplish the required 

actions within the compliance times 

specified, ‘‘unless already done.’’ 

Therefore, if operators have 

accomplished the actions required for 

compliance with this AD before the 

effective date of this AD, no further 

action is necessary. The FAA has not 

revised this AD in this regard. 

Conclusion 

These helicopters have been approved 

by the aviation authority of Canada and 


khammond on DSKJM1Z7X2PROD with RULES
38908 Federal Register / Vol. 86, No. 139 / Friday, July 23, 2021 / Rules and Regulations 

are approved for operation in the United 

States. Pursuant to the FAA’s bilateral 

agreement with Canada, TCCA, its 

technical representative, has notified 

the FAA of the unsafe condition 

described in its AD. The FAA reviewed 

the relevant data, considered the 

comment received, and determined that 

air safety requires adopting this AD as 

proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on these helicopters. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed the following 

service information. This service 

information specifies procedures to 

determine if an affected part is installed, 

and if an affected part is found, 

replacement with a non-affected part. 

These documents are distinct since they 

apply to different helicopter models. 

• Bell Helicopter Alert Service 

Bulletin 206–09–123, Revision A, dated 

June 10, 2009. 

• Bell Helicopter Alert Service 

Bulletin 206L–09–157, Revision A, 

dated June 10, 2009. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

Costs of Compliance 

The FAA estimates that this AD 

affects 1,493 helicopters of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

1 work-hour × $85 per hour = $85 .............................................................................................. $303 $388 $579,284 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on helicopters identified in this 

rulemaking action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Helicopters Model SA–365N, 

SA–365N1, AS–365N2, and AS 365 N3 

helicopters. This AD was prompted by 

a report that damage (scorch marks) was 

found on an internal life raft installation 

that contained a half rescue kit. This AD 

requires identifying the part number 

and serial number of each half rescue kit 

located in the internal life raft 

installation and, depending on the 

findings, inspecting the life raft for 

damage, inspecting the condition of the 

flashlight battery, testing the flashlight 

battery, and replacing the life raft or 

flashlight battery (including the leak 

test) as applicable, as specified in a 

European Aviation Safety Agency (now 

European Union Aviation Safety 

Agency) (EASA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective August 27, 

2021.
